A device for measuring the tack of materials, comprising a first cylinder included in a fixed frame and a second cylinder included in a movable yoke, whose outer surfaces contact each other via a layer of the material to be tested for tack. A pulling tool is also provided to engage the recess of the auger segment and to facilitate the removal of auger segment from the auger shaft in an axially forward direction. The analyzer is adapted to, in response to a PVC event signal from the PVC event detector, generate an autonomic balance indicator as a function of pre-PVC heart rate data and post-PVC heart rate data. The second gradient may be based on a gradient in heat transfer rate to coolant from a map of heat exchanger performance. The stored data record providing the listing of tracked IO requests may then be retrieved when the migrated VM is resumed at the destination host machine to determine the completion status of the IO requests canceled on the origin host machine and complete processing of the same on the destination host machine.
